Evaluation and Repair Tools
Bobby
Bobby was one of the very first web accessibility evaluation tools ever developed. Bobby was sold to Watchfire in 2004 which, in turn, was acquired by IBM in 2007. Although Bobby is no longer available as a free service or standalone product, it is one of the tests included within the IBM Rational Policy Tester Accessibility Edition software, the comprehensive enterprise application for testing websites.
Other options are listed on the W3C Website at: www.w3.org/WAI/eval/Overview.html
Complete List of Web Accessibility Evaluation Tools
Web accessibility evaluation tools are software programs or online services that help determine if a Web site meets accessibility guidelines. While Web accessibility evaluation tools can significantly reduce the time and effort to evaluate Web sites, no tool can automatically determine the accessibility of Web sites.
